"o all wishful-fit muy concern." Re it known ther. l, Aereos Essener, ecitizen of the United States, residing et Glevelend, Cuyahoga county,Ghio, lieve inl c vented. new und useful improvements in iCir-Couplers,of which the follovvin is e specification, reference losing had to t ece coin in ,ving dretvings, in which*- iigure l is e. sectionsl plein ofmy im coupler showing the parte in locked 1; is section on linee ll--lllou, 3' is s sectional pien, and melside vier, showing the pc itic'n; 5is e sectional 1 ig. li sectional side view, showing 'the perte inhnuckietlirovvn position, und. Fig. 7 is e section.- o'n lines Vil: Vilef l invention reiutes to our couplers and is i@ designed te provide ucoupler in which the mejor portion ci the pulling' strains is carriedlouclr' tlirougli the knuckle-teil and is thence trensijnitted to thecoupler heed, and o in which the knuckle pin is relieved of strein, thusenabling the huh of the knuckle und the eersjof the coupler heed .to hemade of heevier section through the utilization of u pivot piu.

-To 'this end l provide e knuckle which is so constructed and supportedby the coupler heed. that' under the heavy. pulling' strains ci service,inospite of the tendency of the knuckle nieve and stretch, the maintero'f the preper between the gusrd volition else reietes to the variousich l' li ve particularly described timed he cn. listening to thedrawings, .fi indicates the coupler heed, B the knuckle, the lock, D theopener, und E the lifter. The knuckle B is pivotefl to the-heed A oy theknuckle pin 2 and the knuckle pin holes in the ears ,3 are so enlargedthat in the operation of the coupier the piu is entirely relieved ofstrain under all normal draft and bufiing stresses. Upon the urinersurface of the knuckleruil and its er eide is located s pulling Se lugor hook li, the forward surface of which is preferably concave and whichcoucts with u couvexly shaped shoulder 5 upon the roof el the couplercavity.'

. To prevent the knuckle teil from bending nose ci the lmuckle will hein' downwardly when it. is under pulling 55 stresses transmitted throughthe hook l to the 'coupler-.heath and from vclisengeging from'thefshoulder 5, 'I provides shelf 6 on the floor ci' the coupler head.The shelfv 6 immediately underlies the rear end of theco knuckle teilwhen in locked position, thus giving enough clearance for thev normalmovements o the knuckle, and providing en eil'ective support againstvertical distortionof the teil and the consequent dise egeentof. thepulling hebk 4 and the Isoull el' 5. V

Upon the upper end lower surfaces ot the knuckle teil, just to the rearof tiie'hub.

7, nre formed inclined projections^8,f8, @D somewhat tf-shaped, whichengage correspondingly inclined recess e9, 9f,on the roof anflpiioor ofthe coupler cad respectively. The projections 8, 8 und recesses 9,9',erel adapted to transmit a portionof the bung and pulling strains, andthey also opereteto. prevent the forward end ofthe knuckle' from bendingoutwardly sway from the guardnrm when subjected to pulling strains.

Under heavy pulling strains .the knuckle 8o has e 'tendencyto pull outof, pleceend.1 with ordinary construction, if the knuckley does pull outof place its hub will travel" sway from the guard am side andthe propergege between the nose of the knuckle und; the guard arm 1'0l Will not bemeintsined. vThis condition, however, is obvieted in nay device, since,if the knuckle pulls forwardly, the forward Walls of the recesses 9:9',and the cooperating forward sides of 90 the projections 8, 8', beingapproximately parallel with the fece of the guardarmi 10, will prevent.the increasing' of the distance between the nose of the knuckle and theguard uri-n. The bosses er on the couplerf '95 ears 3 :assist thesebearings in preventingv lateral movement of the knuckle. Builingbezirings on the coupler head for the knuckle ere provided in the raisedbosses e, on the opposite inner ,surfaces of the coupler eers 3, at y onthe coupler side Well to the rear of the hub, at e', z on the reer Wallsof the recesses 9, 9 through the rear Wells of the projections 8, 8',and et lw, w l on thereer side of theknuckle tail and the side Well ofthe coupler head respectively.

In the drawings the knuckle is shown in the position which it occupiesunder a pulling- 3 0 i 'and its legl/l: will 'coperate with thei-armstrain, that is, there is clearance or.back` lashbetween the rear side wof the rknuckle tail and the side wall fw of the coupler head. It willbennderstood, however, that under builing stresses this clearance willbe taken up and the surfaces w and w will come -into builing contact.There isno buing contact. however, between the rear end of the knuckletail and the coupler head, in any position of the knuckle.

The construction and operation of the other parts of the coupler whichprefer to use with the parts described above, are as.y follows: v

The lock Chas a lat face 12 for locking engagement with thel front facel1 of the f knuckle tail, anda vertical face 13 on 'the lsiflecgpositethe face' l2, for; engagement' with the coupler head.

14 is the leg of the'lock, which eoperates with the opener Dj forlocksettng and'knuc- :kle-throwing, hand' 15 is, the locksettingshoulder. thereon. Onfthe forward side of thelock is a rejection 16which coperates with a shoul er l'n the cou lerheadfor, w rd of the,lock cavity, so t at whenthe l is lifted by the'lifter E, which has asldtted cnnectionwith the rear side of the lodk, the projectionll willengage the shouldei' 17 and the ylock, willf fulcrurnfthereabout 18 50ithe knuckle thrower D, to swing the' khucklefthrower about ,its pivot19, so that thefarin-QO will throw open the knuckle- The knuckleengaging end "of the opener? D has a curved surface which .is ydesignedvtovm'lg.- 1, in such a way that it will throw cooperate withv a surfaceontheunder side .of the knuckle tailas shown 'in'dotted lines the.knuckle by means of a rolling action and withthe minimum amount ofsliding friction, that is, vthe opener is so pivoted with relation tothe length of its knuckle-throw ing-"end, that said end is caused tonieve in 4'substantially-.the same line as the line of .movernentofvthat portion of the knuckle tail with which it coperates. This preventsany binding of the pulling surfaces between the knuckle and the couplerhead,

during the opening movement.

It is:I obvious that many changes may be made in the coupler which lhave described i Witnesses:

and shown herein, without departing from.'

my invention, since- What I claim is:

1. In a car coupler, a coupler head, a knuckle having a tail, inclinedprojections on the knuckle tail, bearingsy in the coupler headcoperating withsaid projections to force the nose of the knuckle as itmoves forwardly under. pulling stresses, toward the guard-arm side ofthe coupler, the corresponding faces of said projections and bearingsbeing arranged tangehtially to the bearing 'on "the hub andysubstantially parfaces on the knuckle being substantially parallel withthe guard arm .face to maintain the nose of the-knuckle substantially atthe same distance from the guard-arm nnder pulling stresses.

3.-In a car coupler, coupler head, a

knuckle and apivot pin therefor, ears on said coupler head to which-saidknuckle -is pivoted, inwardly projecting bosses integral therewith andconcentric with the pivot pinV hole and o less Vdiameter'than said ears,coperati g 'shoulderson the hub of the knuckle, vre'rwardlyv inclinedbearings -orming continnaticns `-of said shoulders arrangedtangentiallythereto and substantially parallel .to the 'guardwarm face,and extending transvereelyv of l thel knuckle tail on'th upper and lower.surfaces thereof, 'and corresponding bearingsfin t 'i coupler head,sind bearingsucomprielngnnean's for causing' the nose of 'the knuckle tovincve` towardv the guard-arm side when thelmuc-- kle moves forwardlyunder pulling stress, ARTHUR J.
